Step-by-step explanation:
3:40 - 1:45= 1:55
Answer:
166 bpm
Step-by-step explanation:
Ian's age = 60
MHR stands for maximum heart rate. There are two methods of calculating the MHR :
1) MHR = 220-age
2) MHR = 217-(0.85×Age)
Both the methods are easy to solve but the most accurate is the second one, hence we use the second method to calculate MHR of Ian.
MHR = 217-(0.85×Age)
= 217-(0.85×60)
166
Since the MHR is calculated in beats per minute (bpm)
Therefore, MHR of Ian = 166bpm
Answer:
Step-by-step explanation:
(Tangent Length)^2 = y*(y + 11) You are going to have to use the quadratic formula on this.
Tangent Length = 7
7^2 = y * (y + 11)
49 = y^2 + 11y
0 = y^2 + 11y - 49
a = 1
b = 11
c = - 49
When you solve this quadratic equation you get
x1 = 3.40 which is the answer you go with.
x2 = -14.40 which can't be used. A negative length has no meaning.
Answer:
Maryanne spent $30 at the farmer's market and craft show.
To calculate how many locally grown plants Maryanne can buy with her $30, we need to subtract the cost of the tie-dyed t-shirt she purchased earlier.
The cost of the tie-dyed t-shirt was $7.50, so we subtract that amount from $30:
$30 - $7.50 = $22.50
Now we know that Maryanne has $22.50 left to spend on locally grown plants. Since each plant costs $2.75, we can calculate how many plants she can buy by dividing the amount she has left by the cost of each plant:
$22.50 ÷ $2.75 = 8
So, Maryanne can buy 8 locally grown plants with her $30.
Step-by-step explanation:
Maryanne has $30 to spend and she purchased a t-shirt for $7.50. She wants to buy locally grown plants for $2.75 each. Maryanne can buy a maximum of 8 plants.
Maryanne brought $30 to spend at her favorite farmer's market and craft show. She purchased a t-shirt for $7.50 and wants to buy some locally grown plants for $2.75 each.
To calculate how many plants Maryanne can buy, we subtract the cost of the t-shirt from her total budget: $30 - $7.50 = $22.50.
Then, we divide the remaining amount by the cost per plant: $22.50 ÷ $2.75 = 8.18 plants.
Since we can't buy a fraction of a plant, Maryanne can buy a maximum of 8 plants.

3y = 3x + 15
Which statements about the system are true? Check all that apply.
The system has one solution.
The system graphs parallel lines.
Both lines have the same slope.
Both lines have the same y-intercept.
The equations graph the same line.
The solution is the intersection of the 2 lines
The true statements about the system are:
Both lines have the same y-intercept.
The solution is the intersection of the two lines
To determine the properties of the system, we can manipulate the equations to a standard form, which is y = mx + b, where m represents the slope and b represents the y-intercept.
2y = x + 10
Divide both sides by 2:
y = (1/2)x + 5
3y = 3x + 15
Divide both sides by 3:
y = x + 5
Both lines have the same y-intercept. The y-intercepts of both equations are 5, so they share the same y-intercept.

The system has one solution, both lines have the same slope and y-intercept, and the solution is the intersection of the two lines.
To determine which statements about the system of linear equations are true, we can analyze the equations. Let's start by putting both equations in slope-intercept form, y = mx + b.
From the equations, we can see that both lines have the same slope, which is 1/2. Therefore, the statements that are true are:
